EBGCESEi F03 THE PRODUCTION. OF A CONTINUOUS F1003 FOR LINO'LEUM, TRIOLINE, OR THE LIKE.

- Ho Drawing. Application filed July 23, 1925, Serial No. 45,694, and in Germany October 24, 1924.

I This invention relates to a process for the production of a continuous floor of linoleum, trioline or the like which not only equalizes the uneveness of the floor surface to be cov- 8 ered but is also foot-warm, sound deadening and elastic so that the life of the cover of linoleum, trioline or the like is increased.

To make a continuous floor of this type peat or peat flour is, rendered water repellent 10 according to the invention, by addition of bitumen, and the product obtained is hardened by being treatedwith magnesium chloride, magnesite or the like.

It has become known to make floor covers from peat with addition of magnesium chlo ride or magnesite, these floor covers ossessing however the inconveniencethat t ey are hygroscopic and must be treated in a dry state only. The floor cover, notwithstanding 3% this dry treatment, in a very short time absorbs great quantitites of water, whereby it loses completely its heat insulating qualities. The water absorbed by the floor cover might further cause decay of adjacent wood or decomposition or" the rear surface of the linoleum or trioline, which is made from jute, or iftlie sub-construction is made of wood, its destruction by dry-rot, owing to the exclusion of air.

This inconvenience is avoided by the process according to the invention for in making'the continuous floor peat is used which is almost completely desiccated and which by the preliminary treatment with-a bituminous water repellent. The same process can be applied to wood fibres or saw dust. The peat, for instance as powdered, prepared with a bituminous material is admixed with commonly used binding agents, for instance 4 magnesium chloride, magnesite, casein, cements, resins of any kind, or chalk and applied in a layer upon the floor to be covered.

The smoothing of the continuous floor is carried out by compression, rolling or the like at cold or hot state according to the kind of binding.

A. continuous floor produced in this manner, if it has hardened, cannot absorb water in a quantity worth mentioning. Accord- 59 ing to the quantity of peat added it becomes more or less elastic and fulfills all conditions to be expected from a supportfor linoleum or trioline.

We claim A process for the production of a continuous floor of linoleum, consisting in desiceating peat or peat flour, rendering the same Water repellent by the addition of coal tar, and in hardening the product obtained, by treating the same with magnesium chloride, and magnesite.

In testimony whereof we aifix our signatures.
